Buy a solid rock reliable SSD M.2

[Char Aznable]

Hi to everyone.
After several days searching in the net for a SSD M.2 to install in my brand new Gigabyte B250 board, i have located these two most common offers available on my country, a Samsung 960 EVO 250gb and a Corsair Force MP500 120gb. But the problem is that i have seen some negative reviews from users about overheating issues, that it failed after a couple of month, that both models have a high failure rates, etc; and i very afraid of making a wrong choice.
Wich brand & model can you recommend me?

PD: Purchasing a liquid cooling system is completely out of the table, very expensive, i only have 1 fan in the case and a desktop fan pointing the airflow to the GTX 560 & motherboard as well, that´s why my concern with a possible overheating with a ssd installed.

Due to high I/O of the drives you've mentioned and the very nature of the drive is fast that it produces heat when the data read/writes are being performed. If you lack proper case airflow, then you should not be looking at surface mounted M.2 NVMe solutions, rather a 2.5" form factor SSD like the Samsung 850 Evo. Make and model of your chassis? Internal specs would offer some light as well.

However I am curious, where are you located? How much do the drives go for in your region?

This is my desktop pc´s specs:

CPU: Intel Core i3 7300 Kaby Lake 3.9GHz processor
Motherboard: Gigabyte B250-HD3 LGA 1151, 4 DDR4, HDMI, M.2, USB 3.0
RAM: Evo Forza 2x8GB DDR4 PC 19200 (2400Mhz)
Video Card: NVidia GeForce GTX 560 TI (Planning to upgrade this to a GTX 1050 TI)
Power Supply: EVGA 500B 80 Plus Bronze 500W 42A
HDD:
-My system disk WD Caviar Green 2TB WD20EZRX
-Seagate Barracuda 4TB ST4000M004 for multimedia storage.

As you can see, the chasis is a pretty standard one, so, even if i can spend a extra bucks with a cooling system, there is no space to put it into; for now, that´s no an option.

Im not very fan of OCing, so, with this configuration, perhaps upgrading the CPU to a i5 Kaby Lake next year, and installing a ssd to balance the proccessing power, i can get a decent low range gaming pc. One question, a ssd m.2 with a not so high data tranfer, 520mb/s write speed and a 540 mb/s read speed, like the M.2 Samsung CM871a 128GB, it heat up to? If that is the case, then i will decide for the Samsung 850 EVO, like you said.
Oh, i almost forgot, i live in cuba, no official pc electronic stores are located here, therefore, a lot of stuff we most buy it on revolico.com, when the mayority of the products are brough from other countries with a Customs tax of 30% and up to 80% of the item value. Here the drives i´ve mentioned in my previous post got a value of $150 and $110 USD respectively.

yes, go the 2.5" samsung 850 evo. You wont notice difference of a fancy 960 m.2 unless you doing massive transfers to another capable drive.
If its just an o/s or gaming drive just go with the 850 and save your $ (and headaches).
